Abstract

LA PRESENTE INVENCION PROPORCIONA UN FILTRO DE RUIDOS LC QUE CONSISTE EN UNA CAPACITANCIA Y UNA INDUCTANCIA, INCLUYENDO UNA PRIMERA CAPA AISLANTE (20) QUE TIENE UNA PLURALIDAD DE PORCIONES (22-1...22-8) DOBLADAS ALTERNATIVAMENTE EN DIRECCIONES OPUESTAS Y APILADAS LA UNA SOBRE LA OTRA, UN PRIMER CONDUCTOR (40) APLICADO A LA CAPA AISLANTE A UN LADO (20A) Y ADAPTADO PARA FORMAR UN ROLLO QUE TIENE UN NUMERO DETERMINADO DE VUELTAS CUANDO LAS PORCIONES DOBLADAS DE ESTA CAPA AISLANTE SE PLIEGAN ALTERNATIVAMENTE EN DIRECCIONES OPUESTAS Y SE APILAN UNA SOBRE OTRA, Y UN SEGUNDO CONDUCTOR APLICADO AL OTRO LADO DE LA CAPA AISLANTE (20B) Y SITUADO EN EL LADO OPUESTO AL PRIMER CONDUCTOR PARA FORMAR UNA CAPACITANCIA ENTRE ELLOS, POR MEDIO DE LA CUAL EL FILTRO PUEDE ELIMINAR LOS RUIDOS QUE PROVENGAN DEL EXTERIOR SIN CREAR NINGUN FENOMENO INDESEABLE COMO UN TIMBRAZO O ALGO POR EL ESTILO.
